There are several issues associated with diving a drysuit that are not encountered with a wetsuit and one of the most concerning is that of being inverted.  Buoyant feet may quickly cause a diver to rise uncontrolably to the surface with all manner of potential DCS issues.  Righting oneself in this situation is straight forward with a single cylinder but not easy with doubles on.  People often arrive at class with fixes for this potential issue such as gaiters (keeping air out of the lower leg) or by adding gas into the wing to keep them slightly chest up in relation to the legs- all good fixes BUT these are fixes to compensate for inability to maintain correct trim- in my classes I teach trim as a key component, be able to control yourself rather than rely upon gear to do that for you.
